Re: A homemade diode power sensor for HP meters

I just purchased 12 pcs without difficulty using a credit card for payment.

They were $4.12 when I added 10 to my cart. Then, when tried to checkout
they suddenly became $9.15 and "We can't process Credit Crd payments at this

Newark became a buggy horror, I was not been able to purchase ANYTHING from
them for last 2 years or so -- there was ALWAYS an issue and their site
never worked since something like couple of years ago.
Do NOT buy anything from them, don't support the incompetence.

Somewhat brute-force but this was a last-minute add to a PCB layout that was headed out for fab.
